The T.35/58 filter was a modernized version of the T.35 filter, issued for military use.

Overview Edit

The T.35/58 is identical to the T.35, save for the following differences:

  • The markings on the side and at the bottom are different
  • The rubber plug at the bottom is slightly different and is attached through a plastic string instead of a twine one
  • The filtering elements were the same used with M.58 filters, with the marking at the bottom explaining the content

When unopened, the filters were stored with two strips of paper over the inlet and the thread. When in storage, they were kept in a polyethylene bag inside a cardboard case. The boxes used for long-term storage contained 24 filters each.
